Description

electrical connector

【Technical field】

The utility model relates to an electrical connector, in particular to an electrical connector with a first insulating body and a second insulating body.

【Background technique】

Please refer to FIG. 8 and FIG. 9 , which show a structure of a conventional electrical connector. The existing electrical connector 10' shown in Figure 8 includes: an insulating body 1', a terminal 2' held on the insulating body, and a shielding shell 3' covering the insulating body, and the insulating body 1' has The base portion and the docking portion extending forward from the base portion have a receiving space 11 ′ recessed on the front end of the docking portion. The terminal is fixed on the insulating body 1 ′, one end has a contact portion protruding into the receiving space 11 ′, and the other end has a welding portion extending backward out of the insulating body.

Please refer to FIG. 9 , which is a cross-sectional view along the line C-C shown in FIG. 8 , and shows the internal structure of the insulating body. The insulative body 1' has a receiving space 11' at the docking part and a plurality of accommodating groove channels 12' which communicate with the accommodating space and pass through the rear end of the base of the insulating body. A wall portion 13'. Due to the structural limitations of the connector, for example, the docking part of the electrical connector needs to have a certain length to maintain a better docking with the docking connector; The housing and the electrical connector are well fixed, so the base must also be of sufficient length. Therefore, the overall size c of the electrical connector in the front-rear direction should generally not be reduced, and the overall size c is generally composed of the size a of the receiving space in the front-back direction and the size b of the channel of the receiving groove. Wherein, if the frame opening of the docking part is not to be deformed, the dimension a of the accommodation space should not be too long, because the overall dimension c of the electrical connector remains unchanged, resulting in a relatively long dimension b of the accommodation groove. During the molding process, The wall portion 13' between the receiving grooves is very easy to break. Conversely, if the channel dimension b of the receiving groove is shortened to prevent the walls between the channels from breaking, the dimension a of the receiving space will be relatively long, so that the frame opening of the abutting portion is easily deformed. Therefore, in the molding process, product quality cannot be guaranteed, which reduces production efficiency.

Therefore, it is indeed necessary to improve the existing electrical connectors to overcome the defects in the prior art.
